This cocktail ring is crafted in Pt900 platinum and features a center natural black opal surrounded by a cluster of natural diamonds. The primary stone is an oval cabochon natural black opal weighing 1.69 carats, exhibiting a vibrant blue and green play-of-color against a dark body tone. The opal is secured by four prongs within a floral-style arrangement. Encircling the center stone is a double-tiered cluster composed of ten round brilliant-cut diamonds and two pear-shaped diamonds positioned at the horizontal axis. These near-colorless natural diamonds have a total weight of 0.86 carats and exhibit VS-SI clarity. The setting features an open gallery and a polished, tapered shank. The interior of the band is stamped with Pt900 for platinum purity, along with the gemstone weights OP 1.69 and 0.86, and a maker or serial code HR0054. The ring is accompanied by a Gem Research Japan Inc. Colored Stone Sorting Memo (No. CS-433176) identifying the center stone as a natural black opal.

Ring size: 6.5 US
Total weight: 5.9 grams.
